摘　　要：报道了一种新型的对绿光敏感的光致聚合物材料,对环境湿度不敏感,材料的干燥时间短。该材料以丙烯酰胺为单体,N-苯基甘氨酸作为引发剂,藻红B作为光敏剂,并加入成膜剂聚乙烯醇及增塑剂二甲亚砜。对材料中光引发剂、光敏剂及增塑剂浓度进行了优化,发现其有一个最佳值。本材料记录的全息图衍射效率可达50%以上,感光强度为60mJ/cm2。在光聚物介质上能够记录信噪比比较高的图像,说明该材料可用于全息存储。A new green-sensitive photopolymer is reported, which is not sensitive to environmental humidity, and the dry time is short. The material was based on acrylamide (AA) as a monomer, N-phenyl glycine (NPG) as photoinitiator, Erythrosin B(ErB) as dye, in addition binder polyvinylalcohol and plasticizer dimethyl sulfoxide (DMSO) was added. The best concentration of NPG, ErB and DMSO is got by optimization of acrylamide-based photopolymes. Diffraction efficiency near 50% is obtained with sensitivity 60 mJ/cm2. The photopolymer can be used to holographic record.
